The King’s Christian generosity in allowing Sarah Ferguson to join him at church on Christmas Day shows that there could even be a way back into the Royal Family for Harry and Meghan.

But first they would have to show some contrition.

That’s the view of The Daily Mail Diary Editor, Richard Eden, writing in the latest edition of his Palace Confidential newsletter.

Her own troubled relationship with the Royal Family meant that Sarah, Duchess of York, had not been seen at the Sandringham Christmas service for more than 30 years.

But that changed on Monday when Fergie joined the royals on parade in front of well-wishers as they made their way to and from church in Norfolk.

‘The King’s embrace of the Duke and Duchess of York shows that there is a way back for the Duke and Duchess of Sussex,’ writes Eden.

‘However, unlike Harry and Meghan, Andrew and Sarah have never attacked the Royal Family. Quite the opposite: they have always lavished praise on their relations.’

King Charles used his Christmas Day broadcast to emphasise that ‘the words of Jesus seem more than ever relevant’, writes Eden – a sentiment supported by his own actions.

‘He demonstrated his capacity for forgiveness by inviting Sarah, Duchess of York to join her ex-husband, Prince Andrew, and senior members of the Royal Family at church in Sandringham.

‘The fact that Andrew was also with the working royals, for the second year running, shows that the King is determined to be a forgiving monarch.

‘His brother was stripped of royal duties by their late mother, Queen Elizabeth, because of his deeply ill-advised friendship with convicted sex offender Jeffrey Epstein.

‘The Duke of York is said to be particularly grateful for the King’s welcome to him and Sarah because he is “tormented” by the forthcoming publication of court documents which are expected to link him to the late Epstein and reignite the sordid scandal.

‘As all Christians know, before forgiveness there needs to be repentance. And we have seen no sign that the California-based couple are prepared to apologise to those they have betrayed with their insults and indiscretions.

‘Until that happens, we may continue to witness the unlikely spectacle of ex-royal Fergie enjoying a more prominent role in the Royal Family than the King’s second son.’
